Biography

My research integrates fieldwork, behavioral, experimental, genomic, and theoretical approaches to understand the ecology and evolution of reproductive interactions. Overarching questions that guide my research program are: (1) How do biotic and abiotic environments interact to influence reproductive interactions, (2) how does this affect the evolution of life-history traits and speciation, and (3) what is the underlying genetic architecture of traits involved in these reproductive interactions? I am currently a Miller Research Fellow at UC Berkeley in Dr. Christopher Martin’s lab. As a Miller Fellow, I am exploring how natural and sexual selection interact to rapidly create many new species by developing new theoretical models and testing them with empirical work on pupfish. My PhD work was with Dr. Suzanne Alonzo at the University of California, Santa Cruz. For my dissertation, I researched how females influence the evolution of male behavior via cryptic female choice (females bias fertilization to specific males), how climate change influences female-sperm interactions, and the role that cryptic female choice might play in speciation. I also develop mathematical models to understand the ecological-evolutionary dynamics of microbe-host interactions in marine invertebrates.

Fisheries Data Analyst
University of California, Santa Cruz
Nov 2022 – Jul 2024 California
I wrote R scripts to analyze and visualize fishery data. This project is helping to inform California Department of Fish and Wildlife’s implementation of the Marine Life Management Act and other policies. Specifically focusing on the socioeconomic and behavioral impacts of domoic acid-related management measures on the state’s crab fisheries and seafood supply systems.
 
 
 
 
 
R Shiny web app developer
Jun 2021 – Nov 2023 California
I developed a R Shiny web app for USAID-Feed the Future Initiative project, “Increasing sustainability of fisheries for resilience of Cambodian communities.” This tool empowers community fisheries management councils in Cambodia to better assess trends in their fishery and make more informed management decisions. This web app features interactive graphs, maps, and allows users to translate between English and Khmer.
